Electromyographic Study of Muscle Fatigue on Patients with Chronic Low Back Pain
نویسندگان
چکیده
Introduction Endurance of the back muscles is considered as an important contributing factor in the development of low back pain. Currently, researchers are looking at reliable methods for measuring the back muscle’s fatigue rate by surface electromyogram (EMG). Many of these studies are still at the experimental stage and the feasibility of using EMG as a clinical tool for such purpose remains uncertain. This study attempts to monitor and quantity muscular endurance of the back muscles through the measurement of surface EMG. The overall objectives of this study are: to measure the rate of fatigue of the back muscles on patients with chronic low back pain (CLBP) by surface EMG; to monitor endurance of back muscles in terms of EMG parameters; to compare these parameters between normal subjects and patients with CLBP; and to investigate the relationship between the median frequency parameters and physical characteristics of the subjects.
